摘要 高压交直流输电线路同走廊架设可以提高输电走廊利用率,但是线路电晕放电会产生混合电场问题。本文搭建平行架设的单极直流导线和单相交流导线实验平台,测量导线不同布置方式下的地面混合电场。在验证混合有限元-有限体积法的有效性基础上,对地面混合电场进行计算。通过实验和计算,获得交流导线电压、导线高度、邻近距离对地面混合电场特性的影响规律。本文的研究结果可为交直流同走廊架设的输电线路设计提供参考。

Abstract:The hybrid HVAC and HVDC transmission lines in one corridor is a solution to improve the utilization of transmission corridors. However, the hybrid electric field due to the corona of transmission lines must be considered. An experimental model including unipolar DC wire parallel with the single-phase AC wire is established in this paper to measure the ground-level hybrid electric field under different arrangements. The ground-level hybrid electric field is also calculated by the combination method of finite element method (FEM) and finite volume method (FVM). Then, the impacts, such as voltage of the AC wire, the height of AC and DC wires and the adjacent distance between DC and AC wires, are researched. It is helpful for the design of hybrid HVAC and HVDC transmission lines.
